Mosfet: PJT138K_R1_00001 not in stock often. Replace with more standard SOT-23 2N7002KT1G

PCB V3 in the works with 2N7002KT1G

Revision done. Sent to manufacture. If no issues testing, will upload gerber.

waiting for the gerber, any update :) ?

I found mistake in the PCB layout. I fixed it, but at the same time, I have changed to a Wemos D1 Mini as it's far easier to find.

The ESP8266 also uses less power, so that should help on the 12/24V BMS with limited output.
JLPCB won't populate the relay chip, but it's not hard to do by hand.

Submitted to JLPCB for manufacture.

When will you share the gerber :) ? I am very much interested in this!

Once I get the prototype in and test it to make sure I didn't screw anything up again. I don't want to release a bad design on the world. I ordered 25, so if it works, I will toss some up on ebay.

@porchthecoder any update on this?
